The mechanism
Every time highly pathogenic avian influenza (HPAI) or African swine fever hits a commercial barn, USDA's Animal and Plant Health Inspection Service (APHIS) doesn't just cut an indemnity check for the culled birds — it changes the compliance bar for the whole facility going forward. Under APHIS's interim final rule effective December 30, 2024, a poultry premises that tests positive for HPAI must now pass a formal biosecurity audit before it can restock and remain eligible for future indemnity. USDA will cost-share up to 75% of the fixes needed to clear that audit. Since the current outbreak began in 2022, APHIS has paid out roughly $1.1 billion in indemnity to over 1,200 producers — and dozens of premises have been reinfected two or three times, meaning the audit-and-upgrade cycle repeats. That's not a one-time federal check. It's a recurring, government-subsidized capital order for testing kits, barn retrofits, and disinfection contracts that lands well outside Tyson's income statement.
